Theory and Design of Electrical Rotating Machinery.
Abstract
The program is for research contributing to new and improved electrical rotating machines, particularly in the area of superconducting motors. One possibility which is being examined is that for a low speed synchronous machine in which both the field and armature windings are superconducting. The design of such a machine is dominated by the A.C. losses which occur in the armature. Most superconducting wire for A.C. operation is a composite made of twisted superconducting filaments embedded in a normal metal matrix. Theory has been developed for the A.C. losses in such wire as a function of magnetic field and frequency over a wide range of conditions. The composite wire is treated as a continuum with anisotropic electrical conductivity. The results are used to design a conductor for a superconducting armature, and some tentative motor designs have been made. (Author)
